Hi,
I have a one critical requirements of finding only locked messages of all WPS 6.0 queues.
Some time we find lots of messages in queues, to find if they are in locked or unlocked, I have to physically visit each queue (Thro admin Console of WPS) and may miss any queue if there are lots of queue holding messages.(locked/unlocked)
The script queueDepth.jacl gives me the depth of the queue, but my requirements would be to list only locked messages depth of all queues, so that I can take immediate action, since all unlocked messages coming after locked messages are not processed.
We have been facing this locked message issue with WPS SIB, when Adapter tries to to poll the queue which has locked messages and hence fails to poll the queue which has locked messages and hence fails, but some time we have observed that even if there are locked messages
the adapter don't fails, but the messages still in the queue so does not allow other unlocked messages to process, hence we have requirements for finding locked messages in queue.

Is this the SIBus entirely, or are you using MQ instead?

Hi jefflowrey,
We are using SIBus not MQSeries...
Have you faced this messages getting locked issue...
If so how do you resolve (We resolve only by restarting the server)
If so how can we can query the depth of all queue giving, so that it only gives locked message depth in each queues ???
Thanks

You need to find out what the real definition of a locked message is.
Is it a message that is not yet committed by the sender or is it a message that is not yet committed by a receiver. Your app might react differently depending on the case.
Are you using transactional gets and puts and are you conservative in the retrieval of messages-- i.e. only allow retrieval of committed messages?.
Remember some of the forward looking features of the JMSEngine like allowing to get uncommitted messages. This should only happen if you are ABSOLUTELY positive that the time between put and commit is infinitesimal.
Enjoy
